the ship my Grandfather arrived in America in 1896

Re: the ship my Grandfather arrived in America in 1896

Joel said 'Frank puts down'. No one on those census records put down anyrhing. The census taker unterviewed someone at the house and the census taker 'put down' the info. Then it was taken to the county courthouse were someone transcribed that info onto the record we view today. How many chances for errors is this?
